Anti-HLA immunization of patients qualified for lung transplantation - Single center study.

For lung transplantation, the presence of donor-specific anti-HLA antibodies (DSA) is an important factor of antibody-mediated rejection (AMR) in its hyperacute, acute or chronic form during long-term follow up. The aim of the study was to assess the allosensitization of Polish patients qualified for a lung transplantation in our center. A retrospective study of 161 potential lung allograft recipients, also of 31 patients transplanted in the University Hospital of Gdansk, between June 2018 and December 2020 were performed.

Ionic homeostasis, acid-base balance and the risk of citrate accumulation in patients after cardiovascular surgery treated with continuous veno-venous haemofiltration with post-dilution regional citrate anticoagulation - An observational case-control study.

Background: Patients after cardiovascular surgery, requiring renal replacement therapy, can benefit from adequate non-heparin circuit anticoagulation. Simplified regional citrate anticoagulation (RCA) protocol proposes the use of citric acid dextrose formula A (ACD-A) during post-dilutional continuous veno-venous hemofiltration (CVVH) with standard bicarbonate buffered calcium containing replacement solution. Citrate accumulation diagnosed upon total to ionized calcium ratio (tCa/iCa) and low ionized calcium (iCa) are considered as the biggest risks related to regional citrate accumulation.

Filter life span in postoperative cardiovascular surgery patients requiring continuous renal replacement therapy, using a postdilution regional citrate anticoagulation continuous hemofiltration circuit.

Background: Regional citrate anticoagulation (RCA) is the recommended standard for continuous renal replacement therapy (CRRT). This study assesses its efficacy in patients admitted to critical care following cardiovascular surgery and the influence of standard antithrombotic agents routinely used in this specific group.

Methods: Consecutive cardiovascular surgery patients treated with postdilution hemofiltration with RCA were included in this prospective observational study.
